Article of footwear 100 is described to comprise vamp 110 and footwear sole construction 120 in Fig. 1 and Fig. 2.The foot that vamp 110 is wearer provides comfortable and covering firmly.Just because of this, foot can be positioned at vamp 110 effectively foot is fixed on to footwear 100.Footwear sole construction 120 is fixed to the lower zone of vamp 110 and extends between vamp 110 and ground.In the time that foot is positioned at vamp 110, footwear sole construction 120 extends with for example attenuates ground reaction forces (namely, for foot provides buffering), provides and adhere to frictional force, improve stability and affect the motion of foot below foot.
For the object of reference, footwear 100 can be divided into three general areas: footwear forward region 101, footwear middle region 102 and heel region 103.Footwear forward region 101 substantially comprise footwear 100 corresponding to toe and the part in joint that is connected metatarsal and phalanx.Footwear middle region 102 comprises the part of the arch area corresponding to foot of footwear 100 substantially.Heel region 103, substantially corresponding to the rear portion of foot, comprises calcaneum.Footwear 100 also comprise lateral surface 104 and medial surface 105, its extend through in the 101-103 of region each and corresponding to the opposite side of footwear 100.More particularly, lateral surface 104 is corresponding to the exterior lateral area (that is, deviating from the surface of another pin) of foot, and medial surface 105 is corresponding to the medial region of foot the surface of another pin (, towards).Region 101-103 and side 104-105 are not intended to distinguish the accurate region of footwear 100.But region 101-103 and side 104-105 are intended to represent that the general areas of footwear 100 helps discussion below.Except footwear 100, region 101-103 and side 104-105 also can be applicable to vamp 110, footwear sole construction 120 with and discrete component.
Vamp 110 by Various Components (is for example described to have, yarn fabric, polymer sheet layer, polymer foam layer, leather, synthetic leather) the conventional in fact structure that forms, these elements are sewn, in conjunction with or otherwise link together to be provided for receiving foot and by structure fixing with respect to footwear sole construction 120 foot.The various element defining cavitys 111 of vamp 110, this cavity 111 is hollow regions of cardinal principle of the shape with foot of footwear 100, it is intended to receive foot.Just because of this, vamp 110 is along the lateral surface of foot, along the medial surface of foot, on foot, around the heel of foot and under foot and extend.The entrance of cavity 111 is provided by being arranged in the ankle opening 112 of heel region 103 at least.Shoestring 113 extend through each lace hole 114 and also allow wearer revise vamp 110 size to adapt to the ratio of foot.More particularly, shoestring 113 allows wearer to tighten up vamp 110 around foot, and shoestring 113 allows wearer to loosen vamp 110 to help foot entering or shifting out from cavity 111 (, through ankle opening 112).In addition, vamp 110 comprises flap 115, and flap 115 extends comfortableness and the adjustability to improve footwear 100 between cavity 111 and shoestring 113.Therefore, vamp 110 is formed by the Various Components of the structure that is formed for receiving and fixing foot.
The main element of footwear sole construction 120 is midsole 130 as described in Fig. 3-6 and footwear outer bottom 140.Midsole 130 generally (is for example formed by polymeric foam, polyurethane foam or ethylene vinyl acetate (ethylvinylacetate) foam), this material in walking, run and other is walked about and between active stage, relaxes ground reaction force (, for foot provides buffering).Although be not described, midsole 130 also can comprise fluid-filled chamber, plate, adjuster or further cushion effect, raising stability or affect other element of the motion of foot.In other structure (it will be discussed below), midsole 130 can mainly be formed by fluid-filled chamber.Although do not exist in some structure, footwear outer bottom 140 is fixed to the lower surface of midsole 130 and forms surperficial at least a portion of the kiss the earth of footwear 100.In order to be provided for the lasting and wear-resisting surface of ground-engaging, footwear outer bottom 140 can be formed by elastomeric material.In addition, footwear outer bottom 140 can have texture to improve the characteristic of adhering to frictional force (namely frictional force) between footwear 100 and ground.Footwear sole construction 120 also can comprise shoe-pad (not shown), and it is to be positioned at cavity 111 and to be close to the lower surface of foot with the compressible member of the comfortableness of raising footwear 100.
Footwear sole construction 120 comprises various features, and this various features provides the advantage of the ability that strengthens bending, the warpage of the footwear 100 in walking with during running or be otherwise out of shape.More particularly, footwear sole construction 120 comprises three bending areas 150, shown in the example of Fig. 3, this bending area 150 is given the specific region flexibility of footwear sole construction 120.In the time wearing footwear 100, due to the ability of footwear sole construction 120 bending enhancing with complying with along with the movement of wearer's foot, therefore, bending area 150 can provide improved comfortableness or movement to the wearer of footwear 100.In continuing the reaction force on buffering ground and giving stability, this flexible increase at footwear sole construction 120 can be provided.
Multiple bending area 150 can be described as be in the region of the thickness of the minimizing in footwear sole construction 120 substantially.In view of the thickness reducing, bending area 150 carries out warpage, bending or is otherwise out of shape to be less than the power in other region of footwear sole construction 120.Bending area 150 is in the multiple region of footwear sole construction 120 and can between side 104 and 105, extend.Although the ad-hoc location of each bending area 150 can marked change, three bending areas 150 are arranged in intersection between 101He Xie middle region, footwear forward region 102 of (a) footwear forward region 101, (b) and (c) footwear middle region 102.With this layout, bending area 150 approaches the location, joint that connects phalanx and metatarsal.The location, joint that, bending area 150 is connected with the other parts of foot around toe.Just because of this, bending area 150 can improve or otherwise help footwear 100 corresponding to the bending connecting in the region in joint of metatarsal and phalanx.
Each in bending area 150 comprises vat 151 and multiple microflute 152.Vat 151 forms relatively large recess and fully extends through footwear sole construction 120 in the surface of the kiss the earth of footwear sole construction 120, as shown in Figure 4.In other structure, one or more in vat 151 can only partly extend through footwear sole construction 120.For example, the part of vat 151 can not be present in the central area (, from the side 104 and 105 both regions of inwardly separating) of footwear sole construction 120.
Microflute 152 is arranged in vat 151 and forms the relatively little recess on the surface of the kiss the earth of footwear sole construction 120.Although microflute 152 approaches each location in side 104 and 105 and extends to the central area of footwear sole construction 120, microflute 152 is not present in central area.Just because of this, the length of vat 151 can be greater than the length of microflute 152.Such as, microflute 152 can have the length that is positioned at the 5%-100% of the length of vat 151 wherein close to this microflute 152.In another one example, single microflute 151 can have the length that is positioned at the 5%-20% of the length of vat 151 wherein close to this microflute 152.In other structure, microflute 152 can fully extend through footwear sole construction 120.
Vat 151 and microflute 152 concur to improve the bending of footwear sole construction 120 in the region of bending area 150.More particularly, each in groove 151 and 152 has reduced the thickness of footwear sole construction 120 effectively, allows thus bending area 150 to come bending, warpage or otherwise distortion with the power in other region of being less than footwear sole construction 120.Although vat 151 has the most degree of depth of the thickness of the minimizing that forms footwear sole construction 120, the multiple microflutes 152 in each in vat 151 have the degree of depth that combines the thickness further to reduce footwear sole construction 120.In the time wearing footwear 100, due to the ability of footwear sole construction 120 bending raising with complying with along with the movement of the foot of wearer, therefore, the groove 151 and 152 in combination provides improved comfortableness or movement to the wearer of footwear 100.
The bending amount providing by bending area 150 depends on many factors, comprises the degree of depth of vat 151.With reference to figure 5 and Fig. 6, one in vat 151 is described to the vicissitudinous degree of depth of tool.More particularly, the degree of depth at each place in side 104 and 105 is greater than the degree of depth in the central area of footwear sole construction 120.Therefore, vat 151 can have taper surface, and wherein the degree of depth is maximum and minimum in the central area of footwear sole construction 120 at 104 and 105 places, side.In order to give significant or favourable amount of bow, vat 151 generally has two ten at least percent the degree of depth of the thickness of footwear sole construction 120.That is, vat 151 forms recess in footwear sole construction 120, and this recess extends through two ten five at least percent of distance between upper surface (, being fixed to the surface of vamp 110) and the surface of kiss the earth of footwear sole construction 120.For example, with reference to figure 6, large 25 percent at the thickness of the footwear sole construction 120 at lateral surface 104 places in the depth ratio of the vat 151 at lateral surface 104 places, and the thickness large 25 percent of footwear sole construction 120 in the central area of the depth ratio footwear sole construction 120 of vat 151 in the central area of footwear sole construction 120.In another example, vat 151 has the degree of depth of about 3-12mm.
Except the degree of depth of vat 151, the bending amount being provided by bending area 150 is also provided the relative depth of microflute 152.For example, microflute 152 can have the degree of depth of about 1-4mm or equal 5% or the more degree of depth of the thickness of footwear sole construction 120.In another example, microflute 152 can have the degree of depth of about 5%-12% of footwear sole construction 120 thickness.In general, in general the degree of depth of vat 151 is obviously greater than the degree of depth of microflute 152.Such as, vat 151 can have the degree of depth doubly than the large 3-5 of the degree of depth of microflute 152.In another example, vat 151 can have than the degree of depth of large 3 times of the degree of depth of microflute 152.Microflute 152 also can be had a vicissitudinous degree of depth.For example, microflute 152 can have tapered structure, and the degree of depth that makes microflute 152 each place in side 104 and 105 is greater than in the central area of footwear sole construction 120 or towards the degree of depth of the central area of footwear sole construction 20.
Discuss as above-mentioned, vat 151 and microflute 152 concur to improve the bending of footwear sole construction 120 in the region of bending area 150.In view of multiple microflutes 152 are present in the specific region of bending area 150, formation has the microflute 152 of 1/3 the degree of depth of the degree of depth that is less than vat 151 and gives sizable addition bend, keeps the structural intergrity of footwear sole construction 120 in the region of microflute 151 simultaneously.
In the structure of above-mentioned discussed footwear sole construction 120, the part of groove 151 and 152 is formed in midsole 130, exposes thus a part for midsole 130.In view of this structure, footwear outer bottom 140 comprises four spaced discrete parts, described in Fig. 2.In addition, the part of footwear outer bottom 140 is separated by corresponding with bending area 150 in position multiple gap.In other structure, footwear outer bottom 140 may extend in the recess in midsole 130 to form multiple groove 151 and 152.In other structure, footwear outer bottom 140 can form separately the recess corresponding to multiple groove 151 and 152.
Based on above discussion, footwear sole construction 120 comprises multiple bending area 150, and this bending area 150 improves the flexural property of footwear 100.Each in bending area 150 comprises multiple recess, particularly vat 151 and microflute 152.Vat 151 forms recess relatively large in footwear sole construction 120, and microflute 152 forms the less recess in the surface of vat 151.In some structure, vat 151 has such degree of depth, this degree of depth (a) extend through footwear sole construction 120 thickness two ten five at least percent and (a) be at least three times of the degree of depth of microflute 152.Vat 151 also can have the length larger than microflute 152.Although vat 151 presents larger length and the degree of depth than microflute 152, groove 151 and 152 concurs to give footwear 100 bendings.
Structure in addition
The structure of footwear sole constructions 120 above-mentioned discussed and described in Fig. 1-6 aims to provide the example of the suitable structure for using at footwear 100.But, the various aspects of footwear sole construction 120 can marked change to affect bending in footwear 100, change other characteristic of footwear 100 and give footwear 100 further features.As example, Fig. 7 A-7C has described each the reformed structure in bending area 150 wherein.
With reference to figure 7A, the bending area 160 that comprises vat 161 and microflute 162 from the side each in 104 and 105 extends internally, but not exclusively extends through the width of footwear sole construction 120.That is, a part for vat 161 is not present in the central area of footwear sole construction 120, forms the gap 166 in vat 161.Another bending area 170 extends to central area from lateral surface 104, but is not present in medial surface 105, thus through about 1/2nd width of footwear sole construction 120.Similar bending area 172 extends to central area from medial surface 105, thus through about 1/3rd width of footwear sole construction 120.
Although many substantially perpendicular to the longitudinal axis of footwear 100 in bending area, Fig. 7 A is described as there is angle with respect to other bending area by bending area 180.For example, the medial extremity 182 of bending area 180 and outboard end 184 can be positioned at diverse location place in the direction of extending between the toe portion of footwear sole construction 120 and heel.Therefore, the longitudinal axis 186 extending along bending area 180 is oriented angled 189 with respect to direction 188, and direction 188 is extending up through footwear sole construction 120 by inner side to the side in outside.Direction 188 can be substantially perpendicular to the longitudinal axis extending between the footwear forward region 101 at footwear sole construction 120 and heel region 103.Such as, angle 189 can be approximately 1 ° to 60 °, or in another example, is approximately 5 ° to 45 °.In addition, although the example of Fig. 7 A is described as medial extremity 182 than the more close footwear of outboard end 184 forward region 101, other embodiment can be provided, and wherein medial extremity 182 is than the more close heel region 103 of outboard end 184.
Another bending area 190 in Fig. 7 A comprises the first end 192 that is greater than the second end 194.By than the second end 194 with larger amount towards footwear forward region 101 with extend heel region 103 and/or by extending to than the darker degree of depth of the second end 194, first end 192 can be larger.In the time expecting larger amount bending in the side at footwear sole construction on than opposite side, this structure may be favourable.Shown in the example at Fig. 7 A, first end 192 can be positioned on medial surface 105 and the second end 194 can be positioned on lateral surface 104.In another embodiment, first end 192 can be positioned on lateral surface 104 and the second end 194 can be positioned on medial surface 105 on the contrary.
With reference to figure 7B, the bending area of footwear sole construction 120 can present multiple other structure.For example, bending area 200 can be included in the non-conical in shape in the direction of extending between side 104,105.In another example, bending area 210 has any place in central area 212 than in side 104 and 105 and has the larger degree of depth or the shape of width.Shown in the example at Fig. 7 B, the central area 212 of bending area 210 can comprise that microflute 214 or central area 212 can not exist microflute 214.Bending area 220 can have angled shape, and the core 222 of bending area 220 is oriented with respect to end 224,226 at an angle.End 224,226 can be with respect to be crossed 120 one-tenth identical angles of footwear sole construction by inner side to lateral direction orientation.
